i To'all whom 'it may concern:

Beit known that I, J om: EVANS CORNELL, a citizen of the United States, residing et Chicago, in the county of Cook and State of Illinois, have invented e certain new and use ful Improvement in Bags, of which the following is a. speeicstion.

My invention relates to begs, erticulerly such as are intended to he lle with owdery or granular suostsnces, end whic i ere designed to he produced in the beg ectory in e substantially complete forni, and to ha then filled and closed Without recourse' to the ordinary methods of closing .the beg, such es sewi or the like.

In t e ecc mpsnying drawings I have illus-v trated onetform of my invention, for a single form Wi l., be sufficient to illustrate the same, though Wish it to be understood that the form showrnisonl one of many.

Figure 1 is a sideeliavation of a bag of my invention, filled. ig. 2 is a plan View of the same. Fig. 3 is aci-oss section on the line 3 3 of Figs. 1 and 2.=..\ Fig. 4 is e. side elevetion of the beg showingthe parts during the process of filling. Fig. `5 is an elevation of filling tube removed.

Lilie parts are indicated by the same letter in all the figures. Y.

A A are the sido portions of the beg and B B the edge portions. These twosides and two edges may, of course, be composed of n single piece of motorini, or of several pieces properly united. The ends of the bags are composed of four-overlapping pieccs, each heine en cxtension of its associated edge or side. For convenience I have letteredv these' portions, `which I will call llaps as follows: C is the outer flop, associated with one of the sides A and C is the under flfep associated with the other side. C is the upper flap associated with one of the edges B, ond C" 1s the under flap associated with the other edge. It is understood, of course, that the division of the elements of the bag into ends, edges, flaps,

the same showing the iilling opening with the sid and the like, is not so much to distinthe bzw is collapsed into a flat condition. Prefero. ly the has consists of o. tube of ma.- terial, one peirof flaps C, C bein foldin the ends of the bag on the diagonal lines D shown in Fig. 5, end the other pair of ila s C, Cl b folding over the corners of the io ds mode y the iist folding process.

The porticuler beg here described is of a. familiar form of manufacture end when it lesves 'the factory is commonly closed at one end. To effect such e closure the four flops are brought together in proper 'relation end by gum, mucilage, or other like materials,

U formed by they ere attached together so es to form the bottom of the bog. The top is ordinarily.

left open. The materiel is then poured into 70 the beg et the top, when th'e four Hops srol brought together et this point, whereuponthey may be secured toget er in any desired manner. This closure of the top o the beg takes leee after the heg has heen lled. l "fit 1 my. invention the bag is brought intrithe complete form indicated in l? 4 and 5`\\ before it is filled, that is to say, the hottom\ is not only permanently closed, but the flaps of the top ore elso in part pernianentl attached to each other in such way es to leave an opening into the beg somewhat es illus tinted. This opening is in this cose formed by gumming the three upper ileps together,

and leaving them seperated from the lower ranged, it will be observed, that the tendency of the material in the hog is to close them or force them together. Abag thus prepared, or prepared in any other manner, but having n 'ii ling aperture analogous to that of the bag illustrated, is then 'filled hy introducing through such opening, preferably b means 100 of s Jilling tube, the material for w ich the bag is intended. As the matoriclfiows into the bsgit rises in the seme underneath one of the two sides of the opening and thustnds to, and eventually does close the filling o en--1\05 ing. On the other hand, as the other sir e of this aperture is formed of overlapping parts D D indicate the creases or folds forme( when which are secured together so es to form, as it wards itby the material within the bag, it is V the two walls of the filling opening and they may be made to adhere together or he other- .geritially or at an ang e to this axis wherever ing {image-way, which enters the ag at one were, a bridge, it cannot give'way and hence, with one. wall of the aperture being held in fixed position and the other being forced toobvious that a ve secure, self-closing filling aperture is former lt is self-closing in the sense that the weight lof the material within the bag causes it to close and remain closed as soon as the filling tube is removed. Of course, the opposite .valls of this filling aperture should be secured together, which can be done by any adhesive material.

The material within the bag tends to close wise secured together. The outer wall is formed as a bridge or arch, against which the inner wall of the o ening sets. This latter inner wall is placed between the outer wall and the material. The direction of the opening into the bag is tangential to its contents as distinguished from the opening into the bagin an ordinary open-mouthed bag. The walls of the opening ma be pasted together or secured in an ot ier convenient manner. The bag which I have shown is a colla sible bag, although of course, it need not e so. It also presents a filled and flattened top and bottom, although this is not indispensable. The adhesive material, if such he used, nia be applied to the bag after it has been fille or may be applied before it is filled, or in connection with the process of filling. v

here l have spoken of the axis of the bag, I niean that axis which is in substantial arallelism with the normal direction of fi ing of the bag if the filling a )erture were of the ordinary construction. t is ,only another wav of stating that mv bag is to be filled tantliis. axis may bc and whether or not it is the short or long axis of the bag.

1 claim:
